Excited to be in Barcelona 🇪🇸 next week for #CHI2026 and share one full paper and one workshop paper on privacy, GenAI, and critical thinking.

Really excited that “Privy” received a CHI ’26 Honorable Mention Award 🏅 Privy is part of my PhD work on AI privacy: understanding AI privacy risks, studying why they’re hard to address in practice, and building tools that help product teams act on them.

Can LLMs really serve as "crash dummies" for security & privacy testing? We put this assumption to the test. 🚨New preprint 🚨: "How Well Can LLM Agents Simulate End-User Security and Privacy Attitudes and Behaviors?" 👇 THREAD 👇 [Link to paper: arxiv.org/abs/2602.184... [1/n]

Excited and grateful to share that I’ve been named a Presidential Fellow by @cylab.bsky.social ! Endless thanks to my advisors @sauvik.me and Jodi Forlizzi, and all my collaborators for their constant inspiration as we work toward shaping the future of privacy-preserving AI.

Congrats to my student @hankhplee.bsky.social for being recognized as one of the 2025 CyLab Presidential fellows! cylab.cmu.edu/news/2025/1...

@cylab.bsky.social wrote a great article on @hankhplee.bsky.social's #chi2025 paper on Purpose Mode. He presented it today and did a great job! PurposeMode reduces distraction on social media from 28% -> 7%. You can use it, too! It's open source :) cylab.cmu.edu/news/2025/04...

Tomorrow (Wed), I will be presenting our @acmtochi.bsky.social paper "Purpose Mode: Reducing Distraction through Toggling Attention Capture Damaging Patterns on Social Media Web Sites" at: - Wed, 30 Apr | 11:22 AM - 11:34 AM | Room G301 - Session link: programs.sigchi.org/chi/2025/my-...

Tomorrow (Mon), I will be presenting our #CHI2025 paper "The Impact of Generative AI on Critical Thinking" at: - Mon, 28 Apr | 4:44 PM | Room G314 + G315 - Session link: programs.sigchi.org/chi/2025/pro...

(Reposts appreciated!) Do you work on user-facing Artificial Intelligence (AI) products? We would like to hear from you! Please fill out this survey to sign up for the study: cmu.ca1.qualtrics.com/jfe/form/SV_...

@yuxuanli1225.bsky.social has been producing great work since day one of his PhD. Can’t wait to see where his brilliant work leads next!

How does using GenAI tools reshape knowledge workers’ critical thinking? Our #CHI2025 paper studied 319 knowledge workers to dive into this question. w/@advaitsarkar.bsky.social @levlevlev.bsky.social Ian, Sean, Richard, Nick @msftresearch.bsky.social @hcii.cmu.edu www.microsoft.com/en-us/resear...

I'm absolutely thrilled to see my recent CHI paper go viral! I’m humbled by all the support and grateful for the thoughtful critiques. Critical thinking in the Generative AI era is more important than ever — stay tuned for more insights soon!

🚨Trapped by infinite scroll & autoplay on social media? Our TOCHI paper introduces a system that reduces distraction by 4x by suppressing these and other dark patterns. Purpose Mode: Reducing Distraction through Toggling ACDPs on Social Media Web Sites 📝 hankhplee.com/papers/purpo...

📣 New paper Privacy harms can seem small in isolation. Viewed in aggregate, however, we realize how creepy surveillance capitalism can be. Unfortunately, these harms go unreported, blurring aggregate impacts. Our #CSCW paper explores how to fix that: sauvikdas.com/papers/56/se... #AcademicSky

I created a starter pack for researchers who work at the nexus of HCI & cybersecurity / privacy here. Please do let me know if you would like to be added to the list!I'm sure I've missed many folks. go.bsky.app/RGsu5jn
